' Philadelphia, county of Philadelphia, and State of Pennsylvania, haveinvented certain new and useful Improvements in lllindstitching SewingMachines, fully described and represented in the following specificationand the accompanying drawings, forming a part of the same. I

The present invention relates to that class of sewing machines which isemployed in felling or making blind stitches upon one side of a fabric,for attaching'a lining, binding, or facing thereto; and in which acurved needle operates wholly upon one side of the fabric.

In the present machine, the cloth or Work-piece to be sewed is laiddirectly upon the iced-arm, and a foot provided with an aperture restsupon theliabric and a needle is oscillated across the aperture iniilinement with the seam, engaging the portion of the fabric which isexposed in the aperture. A raceway in the form of an open trough issupported 'abovethe toot transj needle just as it is being retractedfrom the fabric.

verse to the path or" the needle and also transverse to the line of theseam, with a gap or notch in the middle to iacilitate the passage of theneedle, and a reciprocating shuttle is laid in this open raceway andreciprocated by the shuttlecarrier to take a loop from the A shuttlepointed at both ends is preferable, as it is adapted to engage a loopupon the needle when crossing the path of the latter in eitherdirection, and such a shuttle needs to be oscillated only half asfrequently as the needle. The arrangement of an open-trough racewayabove the foot renders-the shuttle very accessible, and permits it to beplaced in and removed from the raceway with the utmost facility.

The machine is provided with a frame, a goose-neck, and a head upon theouter end of the goose-neck, carrying the stitch-forming mechanism; adriving shaft being extended into the head as usual, to operate suchmechanism. The foot is preferably held stationary upon the head, and thefeed-arm hinged upon the frame tomove to and from the foot, and pressedelastically thereto to clamp the fabric or cloth during the sewingoperation.

The raceway for the shuttle is preferably secured upon the head in afixed relation to the path of the needle, and the foot is adjustableupon the head so as to vary the exposure of the fabric to the point ofthe needle. As the needle ti'avels in a curve, it intersects one cornerof the :raceway,-and the point of the shuttle is therefore formed to liein such corner of the raceway, and notin the middle of the raceway, asis arm, and is preferably made with acentral smooth space betweenmarginal rows of teeth, so that it may press the fabric close to theneedle without danger of the needles engaging the teeth. The smoothcentral space is preferably made level with the tops of the teeth, so asto hold the fabric up as close as possible to the path of the needle.

The feed-Wheel is preferably formed with a short journal upon each endand connected by a universal joint with a teed-arbor in the post oftheirame, such construction permitting a spring to be inserted undereach of the journals to press them elastically toward the fabric, andthus permitting either end of the wheel to yield independently of theother, as is often required in stitching close to the edge of a garment,in which case the pressure and the feeding are thrown chiefly upon oneend of the wheel.

The curved needle is carried by a vibrating arm, and the holder for theneedle upon the arm provided with a thread-guide which delivers thethread directly into a groove upon the under side of the needle; avertical eye near the point of the needle permitting the thread topassupward so that the loop is formed directly on top of the needle, wherethe transversely moving shuttle .can readily engage it.

Atake-up lever is provided, and operated by a cam wvliich permits thethread to follow the extreme for Figure l is a side elevation of themachine; Fig. 2 is a. plan of the same; Fig. 3 is a section on line 33in Fig. 1; Fig. 4 is a front elevation; Fig. 5 is a plan in section justabove the level of the foot M; Fig. 6 is a plan of the foot and racewaywith needle across theraceway; Fig. 7 is an end view of the feed-arm andneedle-arm with the foot, the raceway, and a piece of fabric in section;8 is a front View of the head with the casing cut away to show theinterior, and Fig. 9 is a section of the head, looking toward therearside of the head, and showing the connection for driving the shuttle-armand Fig. 10 is a plan of the head in section, where hatchedj at'thecenter of the. driving-shaft.

ing a loop of the needle-thread; Fig. 1G is asimilar dia gram with theright-hand end of the shuttle engaging a loop;

The machine is shown with a frame having a hollow post A, goose-neck B,and head 0, with a driving-shaft D extended into the head. Ashuttle-shaft E is arranged directly below the drivingshaft andconnected thereto by. gears F, and a rock-shaft G for the needle arm ais shown mounted to turn, and also to reciprocate, in a bearing directlybelow the shuttle-shaft.

Arrangement of fecd-ar'm..-A feed-arm H has forked feet fitted withinthe post A and jointed upon pivots I, and it is extended beneath thehead to carry a feedwheel beneath the needlearm a. A leaf spring J issecured to a seat 1 within the post and projected outwardly between thefeet of the fork to the front end of the iced-arm, and an adjustingscrew K is arranged beneath the spring to produce an upward elasticpressure upon the ieed-arm. The upward movement of the feed-arm undersuch prcssure is limited by a screw L The foot M is'mounted adj ustablyupon the head by a bar M and clamp-screws N, a screw N 2 (having abearing upon the head) being fitted to the upper end of such bar toadjust the foot vertically. A treadle 0 and chain 0 are showndiagrammatically in Fig. 1 to depress the feed arm,- when it isrequisite to insert the garment or fabric to be sewed beneath the foot,i

Shuttle connetions.-The raceway P has division or gap in thepath oftheneedlc, and attached to the rear edge of the head (Figs. 8 and 9),and a doublepointed shuttle Q is vibrated in the raceway byshuttle-carrier R and a shuttle-arm R, having pivot S at one side of thedriving-shaft transverse to the same, and provided with sphericalcrank-pin S A crank upon the shuttle-shaft E is also provided with aspherical Crank-pin, and a connecting-rod T has spherical bearingsfitted o the said crank-pins to oscillate the shuttle-arm as theshuttle-shaft revolves. With this arrangement the raceway lies wholl yabove the foot and is curved in a vertical plane, concentric with thepivot S. The shuttle-arnrR also moves in a vertical plane as its pivotis horizontal. The shuttle-arm R moves in a vertical plane, and as itslower end traverses a curve, the raceway is corresponding] y curved in avertical plane, but its bottom is flat transversely. The

- bottom of the shuttle is therefore flat transversely and curvedlongitudinally to fit the open trough of the raceway,- from which it canbe readily lifted when required. With a (li'inble-pointed shuttle, thegearing revolves the shuttle-shaft at half the speed of the drivingshait, thus permitting the needle to make two oscillations for eachoscillation for the shuttle, and enabling the-opposite ends of theshuttle to engage the loop of the needlethrcadfi'yl'ieh crossing thepath of the needle in either direction, as shown in Figs. 15 and 16.

Construction for zigzag 'sewiny.--The general construction of themachine adapts it for sewing zigzag stitches or a straight scam, thestitches requiring the moving .of the'needle laterally intermediate toits oscillations, so as to intersect the cloth or fabric in twodifferent lines, as shown in Figs. 15 and 16. In

the present invention; such lateral movement of the needle is madeinparallel planes, and is effected by mounting the needl e-ar m a uponarock-shaft G which rock-shaft, a crank b with spherical crank-pin b isattached to the needle-arm (Figs. 10 and 11), and 0s cillated by a link0 which is connected to a spherical crank-pin d rotated by the end ofthe shaft D. The rock-shaft is reciprocated by a connecting-rod f havingone end adjustable in a segment 9, which is vibrated by a crank e and aneedle-cam 6 upon one of the gearwheels F. This connecting-rod is shownarched upwardly to afford more room for the cloth or work-piece upon thefeed-arm. The segment is grooved or slotted to receivelhe connecting-pinf of the rod f, and such groove is extended past the axis of the crank0, so that pin f may remain stationary when set at that point, asrequired when the needle is to oscillate always in the same path, forsewing a straight seam. The connecting-rod f is attached to thepivot-shaft G by a universal joint so as to permit the oscillation ofthe shaft and the movement of the rod f to different inclinations, asthe pin f is adjusted in the segment. The segment g being actuated bythe shuttle-shaft, is vibrated only half as often as the needleoscillates, and it consequently operates intermediate'to theoscillations of the needle to shift it into the two positions requiredfor zigzag sewing. The adjustment of the pin f varies the breadth of thestitches in zigzag sewing. Fig. 7 shows a thick piece of cloth xstretched over the feed-wheel upon the outer end of the feed-arm, with apiece of thin facing or lining it upon its upper side in contact withthe bottom of the foot M. Fig. 6 shows a recess with sloping side in theupper side of the foot, with aperture m through the bottom of therecess, of a width equal to the space between the sections of theraceway, and suitable for the lateral play or movement of the needle insewing zigzag stitch es. A. beveled recess m is also shown at the end ofthe aperture from which the needle advances, to accommodate theneedle-carrier marked a, and Fig. 7 shows the needle n engaged with aportion of the cloth 2; and thefacing u to form a stitch, and retractedpartially from its extreme forward position to loosen the thread andform a loop j with which the pointof the shuttle Q is shown engaged, thesame as in Figs. 15 and 16. As the needle moves through or along theaperture of the foot in orderto penetrate the cloth, it necessarilymoves tangentl'ally to the feed-wheel; as it does not pass through thecloth in forming the stitches, but enters and emerges at adjacentpoints, as clearly shown in Fig. 7.

Thread guide and take-'itp.lhe needle is shown with I a vertical 0 e l.Fi s. 6 and 7) and rooves l/ n 7011 the under side, and the thread isled into such groove by a threadguide 7) attached to thencedle-arm orcarrier close to the shank of the needle. An ear p upon the opposite endof the needle-carrier receives the thread from a gnidearm p whichextends from the needlearm upwardly to receive the thread from a take-uplever V. This lever, as shown in Fig. l2, is actuated by a cam having agroove with. three different seats for the lever-pin o. The cam, asshown in Figs. 1 and 12, is

mounted upon the driving-shaft, and the take-up lever is pivoted at oneside of the shalt and extended across the grooved face of the cam anddownwardly toward the needle-arm to deliver the thread thereto. In Figs.1 and 4, the machine is shown with spool AK, tension so ,the aperture m,and curve the freecorner of the same downwardly sufliciently to pressupon the cloth elasticdeliver the thregd b to the take-up lever. Thelever;

- its highest position gradually downward as the'needle' device B andthreadguides C upon the head which Vs shown in'FE 12 in fulllines in theposition, just before the needle is retracted to form a loop, and it isshown in dotted lines at opposite sides of such position, The camrevolves per arrow V and the lever-pin u is shown engaging the seat '0;of the groove, which is sufficiently eccentric to let the take-up levermove from enters the cloth. The groove then makes a sudden drop to theseat 1), which slackens the thread and per; mits the formation of theloop j upon the needle as the shuttle engages the same, and the seat 1)which connects the portions r and 1/ inclines outwardly from the axis ofthe cam so as to raise the take-up lef'er to its highest position, andtighten the needle-thread upon the shuttle-thread to finish the stitchafter the shutthe has cleared the loop.

Attachments to thefoot.l have found that the needle itannot engagetheiabric uniformly, to make uniform lstitches, with a mere foot havingan aperture or throat through which the cloth can project to engage'aneedle ally and prevent the same from movement, except when carriedforward bythe feed-wheel. To hold the edge of a facing down upon thecloth at either side of the needle,I provide fingersr attachedadjustably to the top of the 'foot, so that they may be set at varyingdistances apart 1 asjniay he required to admit the lateral movement of 1"therieedle in zigzagsewing. Each finger has a straight rib whichprojects downwardly through the aperture m .to the top of the clpth, asshown in Fig. '14, and they ,prevent the edge of, the fabric fromlifting in the aper- A o; the feed 'arm, .which is provided with twocross-bars s ture, on one side or the other, when the stitches are Imade'(as along the tops of trousers bands) so close to the edge of thefabric that ,this'edge rests pon only one iside of the feed-wheel, anddoes not extend across the aperture.

These fingers can be ,adjusted'so as to hold .-the fabric down, nomatter how close the sewing is done .to the edgeoi the fabric. w

' Feeding devices.- Figs. 7 13 and 14 show the outer end having eachavertical slot 3 to form bearings for the journals i of the feed-wheel.The wheel has marginal rows' of teeth w and an intermediate smooth spacew, whichis'preferably made flush with thetops of the i teeth, to pressthe cloth I upwardly, as shown in Fig. 14.-

Or'i oi the journals t is provided with a universal joint t connectingit with a feed-shait t which is extended into'the feed-arm from the postA of the machine, where it isdmrpled to a iced-arbor T having aratchet-wheel 'T" thereonfasishhryn in Figs. 1 and 5. An eccentric 3 onthe feed-shaft oscillatesthe feed-crank u' having the The feed-crank theeed-arba Tflso. that as itis oscillated by the occen 2 is showmas an armpivoted upon piece of Cloth, as'a tric y, the pawl 14, moves back andforth over the teeth of the ratchet-wheel '1 intermittingly, and drivesthe feed-wheel in the required manner.

The ratchet mechanism for turning the feed-arbor is practice madevariable so as to vary the iced; but the construction of the ratchetmechanism is immaterial to the .present invention.

The journals t of the feed-wheel are pressed upwardly" by the oppositeends of a leaf-spring W, and its periphery projects above the top of thefeed-arm, through an opening formed in the same, such projection and theI spring-support W enabling the feed-wheel to yield dur'-" ing theoperation of sewing, when material of greater or' lesser thickness ispassed beneath the foot. The connection of the feed-shaft t with thefeedwheel and the feed-arbor T by universal couplings,

permits the feed-wheel to yield readily when pressed downward by thecloth, and allows one end of the wheel 5 to 'be depressed independentlyof the other where the sewing is done close to the edge of the cloth,and the lat ter therefore presses upon only one end of the feedwheel.The ends of the wheel are rounded, as shown in Fig. 14, to permit it totip between the partitions which form its bearings. j

The yielding support of the feed-arm permits the lat I ter also toyield, if the variations in the thickness of the 5 material excedtheprojection of the feed-wheel from the arm.

From the above description it will be understood" that the raceway and,the needle are arranged in'fixed relations to one another, so that theneedle may always pass beneath the corner of the shuttle. The foot isar-f" ranged between the raceway and the feed-arm, and is preferablyheld stationary, as shown in the drawing,

and the feedarm made to yield for introducing the fab 'l00 ric orwork-piece.

In Fig. 7, 1 have shown the top of the feed-arm curved/in cross sccti6n,and the'bottom of the foot corre' spond ingly curved at one side; but noridge is re quired to bend the cloth for sewing in the present in-?vention, nor is, itnecessary to bend the foot in conform-g ity to sucharidge. Theioot is shown bent downward at one side in Fig. '7, to clearthe end of the carrier which supports and moves the needle; but the footmay be madi flat and the needle-bar or table may be made flat, as shownand claimed in the co-pending ap plication just referred to herein.

In the drawing, the reciprocation of the needle transverse to thefeed-arm, and as the raceway is neccssarily transverse'tothe mode itreciprocates in a plane parallel to the lined the feed arm, with ,thisarrangement; but the relation of these parts to the feed arn1 may bevaried Without departing from the invention.

Where'the rock-shaft for the needle-arm has an adjustahle longitudinalmovement to form zigzag stitches and to vary their breadth, itnecessitates the use of uuiyersalcouplings upon theconn'ecting-rod whichoscillates this shaft, and the movement of the shuttle-arm tastes theuse of universal 'oints upon its connection with the shuttle shaft,-whip ,is made parallel the at right angles t'dtlie oscil\aion oi theneedle necessi- The machine mayzhezopemted for fellingthe folds ofseams,"for joining the edge of a to the edge of a e artrhuserswaistband,- and in quilting the crinoline or stifieningin the lining i"collars, or for any other purpose to which a blind stitching machine isadapted, and can, while engaged in making zigzag stitches, be readilychanged for sewing a straight seam or single lir of stitches, by merelyshiftin; the pin f to the center ol' oscillation of the segment {1; theneedle with whatever kind of stitching always reciprocating in the lineof the seam and not transverse to the same, and taking positions in twoparallel planes alternately, when making zigzag stitches. The width of azigzag seam with this construction is governed solely by thereciprocation of the rock-shalt G and thus differs widely from those inwhich the needle operates transverse to the line of the seam and inwhich the width of the seam is produced and governed by the penetrationoi the needle into the cloth,

With a transverse movement of the needle, such as has'connnonly beenemployed, a greater width of seam can only be secured by penetrating thecloth to a greater depth which is of course prohibited in sewing thinmaterials, whereas, the present construction can form a zigzag scam ofany width upon material of any thickness. A wide zigzag scam cantherefore be made upon thin materials, where it is desired to ornamentthe surface and display colored threads thereon, or a very narrow zigzagseam can be made upon thick mate rial, and unite the layers together,which is impossible vl ith thin materials if the needle operatestransverse to the seam. i v

So far I am aware, my present invention is the first in which areciprocating shuttle has been used in forming zigzag stitches, and as areciprocating shuttle clears the needle thread in a different mannerfrom a rotary shuttle, it enables me to operate twice as fast as if arot ary shuttle were employed to form the stitch.
